Question

0. For her mobile phone service Divya pays 145
per month and 75 paise for each extra minute
she talks over the allowed number of minutes
in the monthly plan. She received a bill of
178 last month. How many extra minutes did
she use her phone beyond the allowed time.​

Answer 1

Step-by-step explanation:

let the number of minutes overtime be x

therefore total amount = 145 + 0.75x

so 178 = 145 + 0.75x

33 = 0.75x

66 = 1.5x

22 = 0.5x

x = 44

So she talked 44mins extra
